TLDR
In this paper, the authors present the effect of DGs on various factors like the Line Losses, Voltage Profile and Network Resonances, and a suitable real-time North American Distribution Feeder is considered along with DGs units.Abstract:
Technological advancement in renewable energy systems and government incentives like Feed In Tariff Program for green electricity generation is motivating utilities around the world to upgrade their existing distribution system infrastructure in order to accommodate increased wind power and photovoltaic (PV) solar power based distributed generation (DG) systems. This paper presents the effect of Distributed Generation Systems on various factors like the Line Losses, Voltage Profile and Network Resonances. A suitable real time North American Distribution Feeder is considered along with Distributed Generation (DG) units. The well-developed graphic facilities available in an industry standard power system package, namely PSCAD/EMTDC for the Network Resonance Study and Distribution Engineering Simulation Software (DESS) for Line Loss and Voltage Profile Study are considered to study the impact of Distributed Generation unit in Distribution Systems.read more
